Sense And Antisense Strands Of Dna

It consists of two strands. Sense strand is the strand of dna that is not used as a template in the process of transcription.

Antisense

Based on the strand that serves as template for mrna formation or transcription one strand is called the sense strand and the other is called the antisense strand.

Sense and antisense strands of dna. Sense and antisense are the two strands of dna. Main difference between sense and antisense strand is that sense strand is incapable of being transcribed into mrna whereas antisense strand serves as the template for the transcription. Dna normally has two strands i e the sense strand and the antisense strand.

For example in microarray expression technologies it is important to know which strand is viewed on the array. The antisense strand of dna is complementary to the sense strand and is the actual template for mrna synthesis. Sense strand vs antisense strand of dna a dna molecule has a double stranded structure.

The two dna strands in the double stranded dna are referred to as sense and the antisense strands. Because of the complementary nature of base pairing between nucleic acid polymers a double stranded dna molecule will be composed of two strands with sequences that are reverse complements of each other. This dna strand is referred to as the antisense strand.

Knowing the difference between the sense and antisense strands is important in certain molecular biology applications. Antisense strand which runs from 3 to 5 direction serves as the template during transcription. The foremost between sense and antisense is primarily based totally on transcription or on the strand that serves as template for mrna one of the strand is called sense whereas the alternative one is called antisense.

The strand that does not code for rna is called the sense strand. To help molecular biologists specifically identify each strand individually the two strands are usually differentiated as the sense strand and the antisense strand. In this article the difference between sense and antisense strands of dna is discussed.

But the resulting rna molecule is exactly identical to the sense strand except for the presence of uracil u instead of thymine t. In double stranded dna only one strand codes for the rna that is translated into protein. The naming of the two strands as sense and antisense is relative to the perspective to the template strand.

Dna molecule is a double helix strand which moreover embrace histones. What is sense strand.
